Eric Milles updated GROOVY-10915:
---------------------------------
    Component/s: Static compilation

> SC: class that provides isCase but not isNotCase
> ------------------------------------------------

>                 Key: GROOVY-10915
>                 URL: https://issues.apache.org/jira/browse/GROOVY-10915
>             Project: Groovy
>          Issue Type: Bug
>          Components: groovy-jdk, Static compilation
>    Affects Versions: 4.0.0
>            Reporter: Eric Milles
>            Priority: Major
>
> Consider the following:
> {code:groovy}
> class C {
>   boolean isCase(value) {
>     // ...
>   }
> }
> {code}
> "x in c" and "!(x in c)" will use C's {{isCase}} method.  However "x !in c" will use {{DGM.isNotCase(c,x)}} which static dispatches to {{DGM.isCase}}.  The isNotCase extension methods added in Groovy 4 should probably use invokeMethod to dynamic dispatch to make use of the isCase implemented by C.
> IMO it would be much simpler to ditch "isNotCase" and have "a \!in b" work identically to "!(a in b)" so one cannot implement incongruent "in" and "!in" handling.
